The Boys in Green suffered a major blow to their chances of World Cup qualification by losing to Sweden at home and the LA Galaxy striker admitted that there was no Plan B
Speaking ahead of the must-win World Cup qualifier against Austria, the LA Galaxy striker said that, ever since he has been involved in international football, the Boys in Green have "always played exactly the same way."
"We talk about 'Plan A' and 'Plan B' and crap like that but Ireland has never had a 'Plan B' before," Keane told reporters in Vienna. "We've always had a 'Plan A', it's a simple as that."
He continued: "Since I came into the squad, we've always played exactly the same way; it hasn't changed from the first minute I walked in that door and I don't think it's going to change for a while."
The 33-year-old, who scored his 60th international goal in the 2-1 defeat against Sweden last Friday added that Ireland simply did not possess the quality to deploy a different approach and suggested following England's lead in attempting to make changes from grass-roots level.
"We don't have the personnel like Spain to get the ball down and have 80 per cent of the possession against other teams. We're just not that team, we know our strengths and we stick to it," he added.
"Unless it changes from grass roots, it's not going to change for a good few years. They keep talking in England about trying to change things and make the national team better and we need to do that as well."
The Republic of Ireland take on Austria in the Ernst-Happel Stadion on Tuesday September 10. Kick off 19:45 BST.
